A force, in the direction of increasing x, acts on an object moving along the x axis. If the magnitude of the force is F = 10·eN, where x is in meters, find the work done by the force as the object moves from x = 0 to x = 2.0 m

plz answer asap! thank you

Expert Solution

Summary: in your question it is given that force is 10.e N. I don't know what this e is representing. I think it is a typing mistake either the force would be 10 Newton or it would be 10x Newton. I solved the problem by taking both the cases. Since the work done is given by the dot product of force and displacement. So first I took small displacement and write down the expression for small work. To find the work in the displacement from x=0 to 2 x =2 metre under the action of force f. I integrated the the work dW by taking the limits from X =0 to X= 2 and got the final value for the work done. In second case assume that force is 10 Newton and solve the problem similarity as above.
